Problem #1: Gmail app on Galaxy Note 4 not syncing properly

Hi there – I have a Samsung Note 4 that is about a year old. I’ve never had this issue until recently and I have not changed anything that I can think of.

All of a sudden the Gmail app is not syncing on its own – I have to open the app and drag down to refresh. Then on the VERY rare event where it does sync, I’m not getting any new email notifications.

I’ve done all the trouble shooting things (reboot, update settings, turn sync off and on, delete account and add it back in, clear cache and data for the app, uninstall updates and go back to factory setup). I’m finding this so frustrating (both the lack of notifications and the lag/lack of sync). FWIW calendar app IS working.

Anything else I can try? Obviously I have all of my settings set for notifications, syncing, etc the way they should be. My husband is a software engineer and can’t figure this out. He installed BlueMail for me and told me to use that but I like the interface of Gmail better since it throws all my promo/social/primary email into separate tabs (and does a darn good job of it). Please help! I have another year of contract on this phone (verizon). — Claire

Solution: Hi Claire. There must be a firmware bug that causes intermittent problems with your Gmail app. If you update Android via over-the-air download from your carrier, the firmware version running on the phone may be coded poorly.

It’s also possible that another app is to blame. If the Gmail app is one of pre-installed apps on your phone, try booting in safe mode and observe it for at least 24 hours. For easy reference, here are the steps how to do it:

  • Turn off the phone completely.
  • Press and hold the Power key and the Volume Down key.
  • When the phone starts to boot, release the Power key but continue holding the Volume Down key until the phone finished restarting.
  • Safe mode will be display at the lower left corner; you may release the Volume Down key now.

If you added Gmail after the initial set up, try to do another round of factory reset, install Gmail app only, and observe the phone for 24 hours. If issue fails to occur either in safe mode or right after a factory reset, that’s your clue to start uninstalling apps until the problem is gone.

Problem #2: Galaxy Note 4 won’t charge after being left for two weeks

After leaving my phone powered off for 2 weeks while I was away it simply will not power on again. I tried charging the battery external to the unit, but actually I’m not sure whether this worked. I also purchased new batteries, but not sure whether these arrive charged or not. I have tried charging the new batteries in the phone (no indication of charging and won’t power up) and in the battery only charger I have. This has always worked OK, but it is a cheap one, so not guaranteed to be perfect. But that’s no reason to think it has failed AND my battery went flat all at same time.

I followed all troubleshooting steps you provide and the phone is just totally dead. Next stop technician unless you have any other ideas? Not sure of Android version as phone out, but phone is Note 4. Thank you. — James

Solution: Hi James. Odds or not, it’s still good to check if using a different charger may make a difference. You can also try to connect the phone to a computer to see if it charges that way, albeit slowly. If nothing changes, even when using a new replacement battery, make sure to have a technician check the integrity of the charging port and circuit board.

Problem #3: Galaxy Note 4 battery drain issue

I have Galaxy Note 4 and it looks like the continuous WIFI scanning problem has started after I downloaded and installed the huge fixes 677 MB size. I turned off all the check boxes, switch etc.  still no luck. It drains the battery like crazy.

Ironically, at home WIFI (relatively weaker signal) – still continuously scans but if I charge it to 100% at 10 PM by 7 AM it is at 98%.  But, at work the signal strength says strong to very strong, but the battery goes from say 93% at 8 AM to 50% by 4 PM. 

 I use my Galaxy Note 4 phone very little and I don’t get that many texts or anything.  I use my desk phone mostly. What is the mystery? — Pundi

Solution: Hi Pundi. We don’t know what apps are installed in your phone but if you have social networking, shopping, and email apps, they may be more actively syncing themselves during daytime than during the evening. Make sure that you check the syncing frequency of all your apps to fix battery brain issue. Better still, try to set the sync process to manual for everything so that only when you tell an app to update will it do so. Keep in mind that multiple apps constantly checking with remote servers for updates can significantly hasten up battery consumption if left unattended.

Problem #4: Mobile data stops working when Galaxy Note 4 screen turns off

Hello, I’m having a problem with my Note 4.

I got this note 4 with AT&T and then I got the unlock code from them, got it unlocked and I’m currently using it outside USA on a different mobile network. I have heard this causes mobile network problems, but up until recently, I haven’t had any problems with that.

The first problem I had was with the WhatsApp app notifications. I have set the app to always show me notifications, and I’ve doubled checked that. However sometimes, when I’m on wifi, and the wifi is working properly, with the phone connected, the app will fail to show me notifications. I will receive the messages but the app won’t show me notifications that I got a message. When I open the app, I will notice that I have messages present that I wasn’t notified about. Even WhatsApp calls won’t appear on my phone. This is the first problem, and it rarely happens, but when it does it’s really annoying. I think it might have something to do with Lollipop, but I’m not sure.

The second problem I started having recently, is the mobile data stops working the moment I turn off the screen. Meaning, the mobile data will be working properly and very fine, but the moment I press the power button and the phone’s display turns off, the mobile data stops working. This now happens everytime I’m on mobile data. I’m not sure if this is connected to the first problem or not, but this is much more important than the first one.

If you can help me I’d be grateful!!

Thank you so much. — Nour

Solution: Hi Nour. We suggest that you first wipe the cache and data of WhatsApp app to try to fix it. An app or OS update may have resulted to a glitch so resetting the app’s state to defaults is a good first try. Here’s how to do it:

  • Go to Settings.
  • Proceed to Applications.
  • Select Manage Applications.
  • Tap the All tab.
  • Look for WhatsApp and tap it.
  • On the App Info page you will see the Clear Cache and Clear Data buttons.

Now, if you suspect that the two issues started appearing after installing Android Lollipop, we recommend that you wipe the cache partition to ensure that the phone’s system cache is refreshed. Following an update, there’s a chance that the cache partition will become disorganized, cluttered, or contain outdated and irrelevant files. While updates like Lollipop are supposed to automatically create a new cache, this does not always happen in reality. One of the main reasons why so many users are complaining about slow performance, lag, or freezing issues after updating to Lollipop is a corrupted cache partition. We think that this is also the reason for your case. If you haven’t tried clearing the cache before, here are the steps to do it:

  • Turn off the Galaxy Note 4 completely.
  • Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  • When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  • When the Android System Recovery shows on the screen, release the Volume Up key.
  • Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  • When the wiping of the cache partition is finished, highlight Reboot system now and hit the power key.

If the previous two procedures won’t do anything, that’s a sign that the most likely culprit is a corrupted firmware. Restoring the phone’s defaults can effectively revert the phone back to its original software condition. Below are the steps to perform a factory reset:

  • Turn off the Galaxy Note 4 completely.
  • Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  • When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  • When the Android System Recovery shows on the screen, release the Volume Up key.
  • Using the Volume Down key, highlight wipe data / factory reset and press the Power key to select it.
  • Now highlight Yes — delete all user data using the Volume Down key and press the Power key to begin the reset.
  • When the master reset is complete, highlight Reboot system now and hit the Power key.
  • The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.

Problem #5: Gmail account on Galaxy Note 4 cannot send email

I can receive but not send email messages from one of my Gmail addresses on my Samsung Galaxy Note 4 cell phone. An error message “select sign key” appears when the “send” icon is tapped. Can you please help me?

Attached are screenshots showing the sequence of trying to send an email. Also shown is information about the email account and the cell phone.  (These shots are numbered.)

I don’t know what a “sign key” is, or what to enter other than the email account password.  Also, I can’t explain why the last error message on the last screenshot, page 10, appears — maybe it says that the password is incorrect?  I’ve both checked and changed the password with no effect.

Thank you. — Robert

Solution: Hi Robert. We can’t seem to open the screenshots you sent to us. We have decided to simply publish your issue without them though.

First off, you have to make sure that your Gmail account is working. Try to log in to the Gmail account in question using a browser like Chrome and check if you can send a test email. If you cannot, make sure to contact Google about.

Now, if your Google account looks okay because you can send and receive normally using a browser, the next step is to ensure that you configure it properly. You need to delete and set it up again using correct server details. For useful information on what to do, make sure to refer to Google’s guide.

Problem #6: Replacement Galaxy Note 4 from T-Mobile is fake

I need  immediate help. I was sent this piece of crap while I was under warranty. I bought and still paying under contract a galaxy Note 4. They send me a replacement with  a refurbished phone that has no serial number, no ID number, made in the USA, plastic cover, no battery compartment, no latch, a generic SD card, a SIM card that is not the mini SIM, it’s quite large with 20 numbers only on it. The phone drains again in less than an hour.

The phone was supposed to be overnighter and I  did not receive it until two days later. I called  to let them know that the package arrived opened and not sealed. I feel like someone has put together this phone and kept the Galaxy that was intended for me. Then I call T-Mobile and the representative said they can’t get anymore Note 4 which I then called Samsung and they told me this is not true. We  can send T-Mobile Galaxy Note 4 with no problem. 

Also how does the SIM card get taken out if I have the phone. This is the 2nd time lookout has sent me a message that the SIM was removed. That’s impossible if it’s in my possession. Could there be an identical match of my phone in someone’s else’s hands?

The applications that came with the phone says it’s incompatible  with my phone. Now how is this possible when some of them never get updated. I have never had one Google update ever in almost  15 months.  I do know this is very important because there has been male are, and other security problems.  I do know for  a fact that without these updates my phone is prone to get one of these security breaches.

Also the video player never works right, starts and stops like it’s streaming over  and over. I did notice now with this new phone my option  for  4G LTE is missing. Why would that disappear when that is what I had. I’m not returning the other phone until this mess is resolved. I bought a Galaxy Note 4, not  a refurbished piece of junk. The  screen broke with one drop. Shattered like a windshield.

Please let me know what I can do and what my options are. I’m not happy about the situation at all. I thought Gorilla Glass was going to help if in case you ever did drop the phone and that is why they exchange the phone out but the song that I have now it’s made completely of plastic and I know Samsung has a better product than this. Why would I pay $500 for junk. It can take a picture of everything if you  like.  I’ve made copies of all numbers all sim cards and SD cards. Which by the way nothing will load onto the SD card. Why?? — Tammie

Solution: Hi Tammie. First of all, we think that the phone you received may be a knock off. T-Mobile IMEI or serial numbers are located outside the back cover directly underneath the battery. If you can’t find a valid serial number on the replacement device, we don’t think there’s any point answering the issues you raise here. The best thing that you can do is to demand a good replacement from either T-Mobile or Samsung. You also need to report the incident that your package was tampered with by the shipper to ensure that an investigation can be conducted.

Please contact us again once you have a genuine phone to begin troubleshooting with.

  1. I have a 2 year old Galaxy Note 4. When I first got the phone I could connect the phone to my PC to transfer files. Over the 2 years there have bee numerous updates, and I had to replace the charger cable. Now when I connect the phone and PC I can see the phone’s icon on the PC but it appears empty. There is usually a message that the Note 4 is unreadable.

    The techs at Verizon have been unable to solve the problem.

    Is the culprit the replacement cable, an update or something else.
